Janet Jackson has been hospitalized with an undisclosed illness, resulting in the abrupt cancellation of last nights (September 29) Rock Witchu Tour Montreal show. A representative for the pop star confirmed she suddenly became ill while completing a routine sound check. The cancellation was announced to disappointed fans just minutes before LL Cool Js opening set. This marks Jacksons second Rock Witchu Tour cancellation in three days, as last Friday (September 27) the singer nixed a show due to production budget constraints. At press time, Jackson, who recently severed ties with Island/Def Jam, remains in stable condition
